Why Americans waste so much food

Even though American consumers throw away about 80 billion pounds of
food a year, only about half are aware that food waste is a problem. Even more,
researchers have identified that most people perceive benefits to throwing food
away, some of which have limited basis in fact.

A
study published in PLOS ONE is just the
second peer-reviewed large-scale consumer survey about food waste and is the
first in the U.S. to identify patterns regarding how Americans form attitudes
on food waste.

The
results provide the data required to develop targeted efforts to reduce the
amount of food that U.S. consumers toss into the garbage each year, said study
co-author Brian Roe,
the McCormick Professor of Agricultural Marketing and Policy at The Ohio State
University.

The
researchers developed a national survey to identify Americans’ awareness and
attitudes regarding food waste. In July 2015, it was administered to 500 people
representative of the U.S. population.

The
study found that 53 percent of respondents said they were aware that food waste
is a problem. This is about 10 percent higher than a Johns Hopkins
study published last year, Roe said, which indicates awareness
of the problem could be growing.

“But
it’s still amazingly low,” he said. “If we can increase awareness of the
problem, consumers are more likely to increase purposeful action to reduce food
waste. You don’t change your behavior if you don’t realize there’s a problem in
the first place.”

Among
other findings, the study identified general patterns that play a role in
people’s attitudes regarding household food waste.

“Generally,
we found that people consider three things regarding food waste,” said doctoral
student Danyi Qi,
who co-authored the study. “They perceive there are practical benefits, such as
a reduced risk of foodborne illness, but at the same time they feel guilty
about wasting food. They also know that their behaviors and how they manage
their household influences how much food they waste.”

In
particular, the survey revealed patterns in how Americans think about food
waste:

Perceived
benefits: 68 percent of respondents believe that throwing away food after the
package date has passed reduces the chance of foodborne illness, and 59 percent
believe some food waste is necessary to be sure meals are fresh and flavorful.

Feelings
of guilt: 77 percent feel a general sense of guilt when throwing away food. At
the same time, only 58 percent indicated they understand that throwing away
food is bad for the environment, and only 42 percent believe wasted food is a
major source of wasted money.

Control:
51 percent said they believe it would be difficult to reduce household food
waste and 42 percent say they don’t have enough time to worry about it. Still, 53
percent admit they waste more food when they buy in bulk or purchase large
quantities during sales. At the same time, 87 percent think they waste less
food than similar households.

In
studying these patterns, the researchers see several areas in which to focus
educational and policy efforts.

“First,
we can do things to chip away at the perceived benefits of wasting food,” Qi
said. “Our study shows that many people feel they derive some type of benefit
by throwing food away, but many of those benefits are not real.”

For
example, removing “Sell by” and “Use by” dates from food packages could
significantly reduce the amount of good food that is trashed, the researchers
said.

“Only
in rare circumstances is that date about food safety, but people are confused about
the array of dates on food packages,” Roe said. Recent efforts to create
uniform national standards for such labels have received bipartisan
support.

In
addition, the researchers see an opportunity to help consumers understand the
negative environmental impacts of food waste.

Food
waste is the largest source of municipal solid waste in the U.S. and the most
destructive type of household waste in terms of greenhouse gas emissions, the
researchers report.

“Helping
people become more aware of that wouldn’t be a silver bullet,” Roe said, “but
it could sway 5 to 10 percent of people who are generally willing to change
their behaviors to improve the environment but who have never put two and two
together about the damaging impacts of food waste.”

Finally,
researchers believe better data on measuring household waste could lead to
improvements.

“Basically,
right now everybody thinks they are doing as good as or better than everybody
else,” Roe said. “It’s somebody else that’s creating food waste.”

To
combat that problem, Roe, Qi and other members of Roe’s research group are
developing a smart phone app to better measure household food waste.

Roe is
seeking federal grants and private support to fund the project, a collaboration
with the Pennington Biomedical Research Center at Louisiana State University.
The LSU group developed the SmartIntake app
several years ago to help participants in food intake studies report what they
eat more accurately.

Funding
for the study came from the McCormick Program in Agricultural Marketing and
Policy, housed in Ohio State’s Department of Agricultural, Environmental and
Development Economics.

Thought for the day

You’d be forgiven if you hadn’t noticed. His verbal bombshells are louder than ever, but Donald J Trump is no longer president of the United States. By having no constructive response to any of the monumental crises now convulsing America, Trump has abdicated his office. He is not governing. He’s golfing, watching cable TV and tweeting…

In reality, Donald Trump doesn’t run the government of the United States. He doesn’t manage anything. He doesn’t organize anyone. He doesn’t administer or oversee or supervise. He doesn’t read memos. He hates meetings. He has no patience for briefings. His White House is in perpetual chaos.
